WiFi not working in the whole of the house

[TimJen]

Hi - our broadband WiFi fails to reach parts of the house, we have sorted out upstairs, but not the back of the house has poor signal. The hub is in an open space, but we have thick walls, so assume the signal isn't getting through. What can be done?

Sky loans wireless booster hardware 'free' under the terms of the 'WiFi Guarantee' element of the legacy 'Broadband Boost' add-on and the 'Enhanced Wall to Wall WiFi Guarantee' part of the 'WiFi Max' subscription supplement: they don't otherwise provide or sell boosters except to resolve issues with Sky Q. Phoning Sky to go through a telephone diagnosis is required to have a booster or pod allocated to the account. Inevitably some  Sky booster hardware has leaked onto a certain auction site and elsewhere online but Sky won't offer support with using these, and Max pods acquired that way won't work at all. 

Confusingly the default 'Wall to Wall WiFi Guarantee' bundled with all new Sky Broadband orders where Boost or Max is not added by the customer doesn't actually provide booster hardware, and is essentially a sales lead generator for the supplements mentioned above plus a one month broadband subscription refund.
